Granted: 2004-08-24
Abstract: Vacuum glazings and methods of manufacture thereof are described; the glazings provide improved shear stress resistance in that the vacuum glazing comprises two sheets of glass (2, 3), hermetically sealed around the edge (4), with a thermally insulating internal vacuum, and an array of support pillars (5) placed between the glass sheets (2, 3), wherein the pillars (5) consist of a core (13), made of a material of higher compressive strength, with at least one end covered by a layer of softer material (14). Alternatively,the vacuum glazing comprises two sheets of glass (2, 3), hermetically sealed around the edge (4), with a thermally insulating vacuum, and an array of support pillars (5) placed between the glass sheets (2,3), wherein the array includes a small number of fused solder glass pillars located over the surface of the glazing, between pillars of higher compressive strength. Advantageously the support pillars (5) comprise two flat parallel ends (15, 16) shaped to provide stable equilibrium, and sides (17) shaped to provide unstable equilibrium, to ensure that the pillars when placed on a glass sheet will fall onto one of the flat faces (15, 16) and thereafter lie on that face.

Title: Fiber-optic transceiver for combined serial data and time code communication
Inventor: MINTEER TIMOTHY M
IPC: H04B10/152
Filed: 1997-04-24
Granted: 2002-07-09
Abstract: The fiber-optic transceiver system combines EIA-232 data with IRIG-B time code information in a time multiplexing  arrangement.    The  combined  signal  is transmitted  to  a  receiver  where  the  time  code information is decombined from the data, so that the two signals are replicas of their originals.   The time multiplexing is accomplished by inserting a pulse into the data stream following the occurrence of a minimum time for each data bit and the coincidence of a time code pulse.

Abstract: A peel seal zipper tape for reclosable plastic bags  or  packages  includes  a  first  and  a  second mutually interlocking zipper profile disposed on a top surface of a laminated film strip.  The top surface is formed  by  a  layer  of  a  sealant  material.    The laminated film strip also has a bottom surface formed by a layer of a non-peel-seal material.  In use, the laminated film strip  is  folded over enabling  the zipper profiles to be interlocked with one another. In so doing,  portions of  the  top surface of  the laminated film strip face one another, so that they may be joined with a heat seal.  The outside of the folded peel seal zipper tape,  that is,  the bottom surface  of  non-peel-seal  material,  is  bonded  to plastic sheet material from which reclosable plastic bags or packages are made.  In the production of the bags or packages, the mutually facing portions of the laminated  film  strip  are  sealed  together.   The resulting seal gives a visual indication of having been broken when initially opened.

Abstract: This invention provides learning methods in binary systems by modifying the connected states of the circuit among each basic binary gate in binary combined logical and sequential circuits composed with basic binary gates such as AND, OR, NOT, NAND, NOR and EXOR gates. As the pseudo-neuron theory and the pseudo-potential energy theory are skillfully introduced, it is possible to attain specified learning effects during a very short learning period.   Further,  as implementation of the learning methods into the conventional computer and other digital equipment is simple, it is expected to be used widely in wide application, for example, such as in image processing, voice processing or natural word processing.

Abstract: A check valve connectable in a refrigerant line is economically fabricated from only three parts  -  (1)  a copper tubing body connectable in the refrigerant line, (2) a nonmetallic shutoff ball, and (3) an annular valve seat member having a conically tapered seating surface on one of its ends.  The seat member is coaxially received within a first end of a longitudinally central portion of the tubing positioned between spun-down opposite end portions thereof, with the seating surface end of the seat member facing the second end of the central tubing portion,  and the ball being received in the central tubing portion for axial movement  into  and out  of  sealing  engagement  with the seating surface.  Three circumferentially spaced, axially elongated side wall indentations are formed in the central tubing portion  .   The indentations have  (1)  first end portions which, with the first end of the central tubing portion, axially locks the seat member within the central tubing portion, (2) second end portions that combinatively form an axial stop for the ball, and (3) main body portions that combinatively form within the central tubing portion a track structure that axially guides the ball between its closed position against the seating surface and its open position against the axial stop.  When the ball is in its open position against the axial stop,  refrigerant flows through the interior of the valve seating member and then around  the  ball  via  circumferentially  spaced,  axially extending fluid bypass passages positioned between the tubing side wall indentations.

Abstract: An apparatus and a method are provided to monitor a generally transparent blood tube at a location that is downstream from a blood separator in order to detect the presence of red blood cells in a tube that is intended to carry a different blood component, for example platelets. A red light source and a green light source are located id relation to the tube so that red light emission and green light emission are directed toward the tube and toward the flowing blood component(s) that is carried within the tube. The red light source produces a red reflection intensity from red blood cells whose magnitude increases as a function of an increase in the concentration of red blood cells. The green light source produces a green reflection intensity from the red blood cells whose magnitude decreases as a function of an increase in the concentration of the red blood cells. These two light reflections are sensed by means of one broadband photodetector, or by two band-specific photodetectors, that are located on the same side of the tube, so as to be responsive only to reflected light. An output is provided by detecting the ratio of the magnitude of the red reflection intensity to the magnitude of the green reflection intensity.

Abstract: A download decision section decides whether or not an electronic mail received by a mail communication section is a DL instruction message indicative of an instruction for downloading a program. A notification/instruction section puts on a light of a lamp when the download instruction message is received, and outputs a download execution instruction when a confirmation button with lamp is pushed down. A DL execution section executes a download of the program according to a download execution instruction. The download execution section generates a download request message to a downloaded data storage server via the mail communication section, and extracts the program from a program attached electronic mail transmitted from the downloaded data storage server.      Accordingly, it is possible to make a rewrite of data easier and to process various types of data.      The above-mentioned processing thus facilitates a rewrite of data and enables various types of data to be processed.
